REASSEMBLY PROCEDURE

First Stage Reassembly

CAUTION: Before proceeding, visually inspect the

cylinder according to Compressed Gas Association

(CGA) standards pamphlet (CGA C-6.1--2002, "STAN-

DARDS FOR VISUAL INSPECTION OF HIGH PRESSURE

ALUMINUM COMPRESSED GAS CYLINDERS"). This

inspection requires a visual inspection light. If the

cylinder does not pass the visual inspection, it must

be serviced or replaced with a new cylinder before it

can be assembled and lled.

1. Install a new, lightly lubricated o-ring (37) over the cylin-

der threads so that it is seated against the rst stage body.

Lubricate the rst 4 to 5 threads on the rst stage body with

Christo-lube

2. Thread the rst stage into the cylinder until hand tight.

Attach a 1 3/16" crowfoot adapter to a torque wrench. Place

in cylinder vise or apply a strap wrench to the cylinder. While

holding the cylinder rmly, torque the rst stage body to a

torque value of 25±2 ft/lbs.

3. Install a new, lubricated piston shaft o-ring (33) and pis-

ton head o-ring (31) onto the piston (32). Closely inspect the

edges of new HP seat (34). One edge is sharp and one edge

has a chamfer. With the chamfered edge facing outward,

press the HP seat into the small, recessed hole in the end of

the piston. Put the piston down on a clean, hard, at surface

to seat completely.

4. Place the spring (35) into the body. Press the piston into

the cap (30) so that the piston head is seated at against the

cap. Lightly lubricate the male threads on the body.

5. Pass the piston shaft through the spring. While pressing

down on the cap, hand tighten the cap onto the rst stage by

turning clockwise. Tighten the cap with an adjustable span-

ner wrench (p/n 107394) until the cap stops against the rst

stage body.

6. Install a new, lubricated o-ring (25) onto the shaft of the

check valve (26). Install a new, lubricated o-ring (22) onto the

ll port plug (21).

7. Install a new, lubricated o-ring (22) onto the ll adapter

port. Insert the check valve (26), o-ring side rst, into the

male-threaded end of the ll adapter port (23).
